摘要
在轨道交通线路周围进行工程活动而又要确保已有轨道交通线路的正常运营,必须严格控制施工对运营线路的影响。针对在运营地铁邻近的基坑施工工程,介绍了工程的设计中基坑围护方案、地铁的保护措施和基坑分块挖土方案,详细分析了施工过程中引起地铁隧道最终变形的规律和施工各阶段地铁隧道变形的规律。该工程采取的控制地铁隧道变形措施是有效的,可供类似工程参考。
It must be controlled strictly that the influence of project construction, when the project is circling some operating rail lines. Aiming at an foundation pit project nearing operating rail lines, the foundation pit surrounding plan, protection measures and partition excavation plan were introduced. The ultimate deformation rule of rail tunnels during the construction process and different rules during different construction period were analyzed in details. The controlling measures were effective that can provide reference for similar projects.
